Product Details

Protect your hair from heat damage with the Kérastase Extentioniste Thermique. This gel-cream formula strengthens your locks to prevent split ends and damaged tresses.

The Extentioniste Thermique is a lightweight, gentle formulation which restores hair without causing any tension or breakages. This leave-in treatment is the perfect way to protect your precious lock by sealing hair lengths. Once the cream is applied it gets to work by encouraging elasticity, while also adding a boost of hydration. Not to mention, it protects hair up to heat of 230°C, so is perfect to use with heat styling tools.

The formula is enriched with a nourishing combination of glaçage thermo-ceal, creatine R™ and taurine. These active ingredients are full of amino acids and lipids which are responsible for strengthening your hair fibre and creating a healthy scalp environment.

Product Features

Kérastase Extentioniste Thermique is built to target shiny hair.

This Kérastase Extentioniste Thermique contains salicylic acid which helps to prevent oil build-up.

Kérastase says

"Our thermo-protecting blowdry and heat-styling cream is designed to seal lengths and split ends. Its combination of Glaçage Thermo-Ceal + Creatine R + Taurine seals and resurfaces the hair fiber, reducing the breakage by 93% after one application. Hair is strong, resistant and can grow longer."

How To Use

  1. Make sure your hair is clean
  2. Work the gel-cream through the lengths of your damp hair
  3. Create your beautiful hairdo with your favourite heat styling tools
